Swing Trader; No need to sit in front of a computer all day, more time to do other things.
True, but a short term trader doesn't have to do a full shift. 2-3 hours can work really well.
For example, a US trader (East coast), can trade 6am-8am before work. FX has plenty of action.
An Asian/Aussy trader can do 5pm-7pm or even later and catch plenty of Euro timeframe action.
A European trader can work 7pm-9pm and trade the US.
All of the above can be done when working most regular jobs assuming 9-5pm. In fact, it's a great way to work into a full time trading gig with little risk to capital (trade really small), and almost zero pressure to perform and make money (regular job provides the income).
Perfect your strategies while working a regular job and if you learn the needed skills go full time. Throw in 2-4 hours of sim trading over the weekend and that's 10-15 hours training every week. That would be around 2,000 hours over 3 years. 3 years of solid work and you're going to get a pretty good feeling if you can make it. If not, cut your losses and re-apply full focus on your current job. Trading isn't for everyone but better to have a go and fail rather than never have a go and never know...
